,1 Claim.

The present invention relates to demountable rims for vehicle wheels and has forits primary object to provide a rim structure embodyingan entire supporting surface for a pneumatic tire and in which the tire is adapted to be removed from the wheel together with the ri Afurther object isto provide a novel attaching construction for the rim whereby the rim is positively secured in position on the wheel without danger of the rim becoming accidentally displaced thereon.

A still further object is to provide a demountable rim of this character adapted for use upon disk and other types of wheels and also including a cover plate for the outer surface of the wheel which provides a shield for the attaching bolt for the rim.

A still further object is to provide a wheel construction of this character of simple and. practical form, which is strong and durable, which may be easily and quickly removed for demounting the tire and otherwise well adapted for the purposes for which the same is intended.

Other objects and advantages reside in the details of construction and operation as more fully hereinafter desscribed and claimed, reference being had to the accompanying drawings forming part hereof, wherein like numerals refer to like parts throughout, and in which- 1 Figure 1 is an outside elevational view of the wheel with the tire mounted thereon and with parts broken away,

Figure 2 is a similar view of the inner side of the wheel,

Figure 3 is a vertical sectional view taken substantially on a line 3-8 of Figure 1, and

Figure 4 isa fragmentary side elevational view with parts broken away and shown in section.

Referring now to the drawings in detail, wherein for the purpose of illustration I have disclosed a preferred embodiment of the invention, the numeral I designates the vehicle wheel of disk form mounted on the axle i by means of bolts 1. The wheel includes the felly construction I which is of channel form, the inner edge of which is formed with the outwardly extending tire-engaging flange i. The outer peripheral edges of the felly are inclined downwardly toward the outside of the wheel as shown at It and seated on the inclined surface of the outer periphery of the felly is the rim designated-generally at H. The inner edge of the rim II is adapted to abut the flange I and the outer edge of the rim is formed with the outwardly extending flange l2, the tire II being seated on the outer periphery of the rim between the flanges 9 and I! as more clearly shown in Figure 3 of the drawings.

Aninwardly projecting flange I4 is formed on the inner periphery of the rim Ii, adjacent its outer edge and is positioned fiatwise against the outer surface of the telly 8. The outer surface of the felly is provided with spaced recesses is within which substantially conical lugs it are conformably seated. Rim attaching bolts ll are inserted transversely through the telly and through the lugs or bosses It, the inner ends of the bolts being provided with left-hand threads 20 for threaded engagement in the inner wall of the telly while the outer end of the bolt is formed with oppositely formed threads 2! which are threaded in the boss or lug It. The inner end of the bolts may be provided with screw heads 22 while nuts 23 are threaded on the outer ends of the bolts and countersunk in the outer surface of the flange it.

A substantially U-shaped bracket 24 projects outwardly from the hub 6 with the ends of the bracket anchored in position by the bolts 7, the bight portion of the bracket providing anchoring means for a screw 25 which is threaded through the concavo-convex central portion 28 of a shield 2'! which covers the outer surface of the wheel, the outer periphery of the shield l8 bearing against the flange It at a point radially outwardly from the nuts 23 of the bolts l'i.

The tire valve 29 extends through the shield ,21 to permit inflation of the line without removing the shield.

It is believed the details of construction and manner of use of the device will be readily understood from the foregoing without further detailed explanation.

Having thus described the invention, what I claim is:

A vehicle wheel including a felly having a bottom and sides at right angles to said bottom whereby said felly is transversely U-shaped, and an outwardly extending tire retaining flange on one side, a rim portion positioned on the felly radially outwardly thereof and having one edge adapted to abut the tire retaining flange of the felly, said rim portion supporting a tire entirely thereon, a tire retaining flange on the other edge of the rim portion and cooperating with the first named flange to retain the tire on the rim portion, said rim portion having an inwardly extending flange adapted for hearing against one side of the felly, conical recesses in the said one side of the felly, conical protuberances on the abutting side of the last named flange adapted to conformably seat in said recesses said recesses and protuberances having bores therein and bolts removably received in said bores for securing said last named flange to the felly, said protuberances serving to aline the bores.
